  • the bracket 19 has plural through-holes 20, 20... at the upper and lower portions and the rear portion of the bracket 19.
  • the through holes 20 are arranged side-by-side in the left and right direction and communicate the space at a rear of the fry controller 18 with the outside.
  • the through-holes 20 form a cooling path 21 which enables ventilation at the rear of the fry controller 18.
  • the housing 2 is formed and partitioned to have air passages 22, 22 extending in the front and rear directions and provided on the left and the right of the oil vat 3 and at the upper end in the housing 2, such that front portions of the air passages 22 communicate with the cooling path 21 of the bracket 19.
  • an external pipe 23 that surrounds the exhaust pipe 9 coaxially and has a tapered exhaust port 24 of which sectional opening area becomes gradually smaller near the upper end of the exhaust pipe 9 is provided upright. The lower end of this external pipe 23 communicates with the left and right air passages 22, 22 in the housing 2.
  • the burner controller 17 rotates the fan 12 for a predetermined time to supply air, and thereafter combusts intermittently the mixed gas in the combustion chamber 6 to operate the pulse burner 4.
  • the pulse burner 4 operates repeatedly the operation of combusting intermittently the mixed gas in the combustion chamber 6 to exhaust forcedly the combustion exhaust gas by increase in pressure in the combustion chamber 6 which is caused by its combustion, and the operation of inhaling the fuel gas and the combustion air in the combustion chamber 6 which is put in the negative pressure state due to the exhaust of the combustion exhaust gas.
  • the pulse burner 4 By this ON/OFF operation of the pulse burner 4, the oil is heated to the cooking temperature and thereafter the cooking temperature is maintained. Accordingly, as soon as the foods are input into the oil vat 3 through a basket, they are heated and cooked by the oil of the high temperature.
  • the cooling path 21 through which the air can pass is formed at the rear of the fry controller 18 in the housing 2, while the external pipe 23 is provided at the rear of the housing 2 which surrounds the exhaust pipe 9 and has the exhaust port 24 of which the sectional opening area is made gradually smaller toward the upper end of the exhaust pipe 9.
  • the cooling path 21 and the external pipe 23 are connected through the air passages 22 formed in the housing 2 thereby to form the flow of air such that the air is inhaled into the external pipe 23 through the cooling path 21 and the air passages 22 following the exhaust of the combustion exhaust gas from the exhaust pipe 9, and the air is exhausted from the exhaust port 24.
  • the fry controller 18 can be cooled.
  • the cooling fan is not required, and the increase in temperature of the fry controller 18 can be effectively suppressed with the simple structure which allows small increase in cost. Further, since the position of the fry controller 18 is as before, the usability is not impaired.
  • the fry controller 18 is supported in the housing 2 through the bracket 19 having space at the rear of the fry controller 18, and the through-hole 20 for communicating the space with the outside is provided in the bracket 19 thereby to form the cooling path 21, whereby the cooling path 21 can be easily formed by means of the bracket 19.
  • the pulse burner 4 is used as the combusting and heating unit.
  • the pulse burner 4 combusts intermittently the mixed gas of the fuel gas and combustion air in the combustion chamber 6, exhausts forcedly the combustion exhaust gas due to the increase of the pressure in the combustion chamber 6 caused by the combustion, and inhales the fuel gas and the combustion air in the combustion chamber 6 which is put in the negative pressure state by the exhaust of the combustion exhaust gas. Therefore, there is provided a rational structure in which the ventilation in the cooling path 21 is possible by means of the exhaust operation of the combustion exhaust gas by the pulse burner 4.
  • left and right air passages 22 provided at the upper portion of a housing 2 are extended respectively through hoses 25 and connected to a fan 12. Namely, a cooling path 21 and air passages 22 are connected to an air supply system of a pulse burner 4.
  • a burner controller 17 rotates the fan 12 for a predetermined time for purpose of air supply. Thereafter, the burner controller 17 operates the pulse burner 4 to execute ON/OFF control. At this time, by exhaust of combustion exhaust gas from a combustion chamber 6, the inside of the combustion chamber 6 is put in a negative pressure state. Therefore, fuel gas is taken into the combustion chamber 6, while the outside combustion air flows from the front of the housing 2, passes through the cooling path 21, the air passages 22, the hoses 25 and the fan 12, and is taken into the combustion chamber 6 through a muffler 13 and an air supply pipe 14. By this flow of combustion air, the fry controller 18 is resultantly cooled from its rear surface.
  • the cooling path 21 through which air can pass is formed at the rear of the fry controller 18 in the housing 2; the fan 12 and the cooling path 21 are connected through the air passages 22 formed in the housing 2; and the fry controller 18 can be cooled by the flow of combustion air taken into the air supply pipe 14 through the cooling path 21 and the air passages 22.
  • the cooling fan is not required, and the increase in temperature of the fry controller 18 can be effectively suppressed with the simple structure in which the increase in cost is small. Further, since the position of the fry controller 18 is as before, the usability is not impaired.
  • the cooling path is formed by the through-hole provided in the bracket.
  • the concrete structure can be appropriately modified.
  • space or a groove communicating with the outside may be provided as a cooling path at the rear of the fry controller and on the front surface of the housing.
  • the location of the cooling path is not limited to the rear space of the fry controller, but the cooling path may be formed around the fry controller.
  • each embodiment adopts the structure in which only one exhaust pipe is provided.
  • each of the exhaust pipes may be accommodated in respective one of external pipes having similarly an exhaust port, and air passages may be provided so as to accommodate with all the external pipes; or all the exhaust pipes may be accommodated in an external pipe having an oblong section, and an exhaust port of which the sectional opening area becomes gradually smaller near an opening of each exhaust pipe may be provided.
  • the shape of the exhaust port is not limited to the tapered form, but may be changed such that the exhaust port is obtained by plural recess portions formed intermittently in the circumferential direction.
  • a cylinder or a ring-shaped plate body which is another member from the external pipe and narrows a flowing path may be accommodated in the external pipe thereby to provide an exhaust port.
  • the design of the air passage may be appropriately changed such that the air passage uses the hose in the first embodiment or is formed by partitioning the space in the housing in the second embodiment.
  • the combusting and heating unit is not limited to the pulse burner but a gas burner may used as the combusting and heating unit.
  • the fryer is not limited to the type having a single oil vat, but may be a type having a pair of oil vats. In any case, the invention is applicable. Further, when a fryer takes forcedly the combustion air thereinto by means of a gas burner and with an air supply fan, the flow of air is formed in the cooling path and the air passage by the fan.
